HORSE HAY RAKE.

EEPECIFICATIOIZI' forming part of Letters Patent. 321,-?72, dated July 7, 1885.

Application filed August 18, 1584. (No model.)

To all whont it may concern.-

Be it known that I, Janus Annnnson, a citizen of the United States, residing at Oshtcino,county of Kalainazoofitate of Michigan, have invented a new and useful Improvement in Horse Hay-Rakes, of which the following is a specification.

This invention has for its object a construction whereby the teeth of a sulky hay-rake are locked in their used position.

The invention is especially applicable to the style of self-dumping rakes herein illustratcd.

In the drawings forming a part of this specification, Figure 1 is a side elevation of a rake embodying the invention; Fig. 2, a vertical section of parts enlarged. Fig. 8 is a top view of port-ions of Fig. 2, and Fig. 4 is a vertical section of portions in Fig. 2 on line 2 2.

The head E F of the raketeeth T is connected, in the usual manner, to the axle of the rake. Centrally located is a ratchet-wheel, o, secured to the axle. In the rear of the wheel n is a pawl, a, pivotally connected with the beam F of the rake-head. The upper end of the pawl a is adapted to engage the teeth of the whcol'v. A chain, 1', connects the upper end of the pawl a with a footlreadle, i. A bar, 0, is secured to the rake-frame P, and terminates in a hook in a position to engage with the lower hooked end of the pawl a.

Y is a spring to cause the pawl a to engage the heck of bar (2.

In the operation, by pressing down on the foot-treadle i, the upper end of the pivoted pawl a is brought into position to engage the teeth of the wheel '12, which causes the raketeeth to dump or rise up and pass over the windrow, as in prior devices; but when the foot-treadle t is released, after passing the windrow, the raketceth fall to their used position, and are locked in said position by the engagement of the lower end of the pawl (L with the hooked end of the lock-bar c, as before stated.

If desired, the lock-bar may be made adjnstablc to govern the degree of the pressure of the teeth on the ground. This is illustrated in Figs. 2 and i. A support or bracing casting, a, is secured to the frame I, and provided at the lower end with a loop, a, through which the lock-bar c is passed. The upper end of the lock-bar is slotted, and in said slot the securing-bolt a is located. Thus by loos ening said bolt and slipping the bar 0 the position of said bar may be changed. The ob ject of thus locking the teeth in their used position is to obviate the necessity of holding them down by manual eiiort. A trip-bar, c, is secured to the frame in a position to engage with the upper end of the pawl a, to disengage said pawl from the ratchet-wheel '0 after dumping the rake.

Having thus described my invent-ion, what I claim as new,.and desire to secure by Letters Patent, is'

1. In a self-dumpingrake, the combination of the rake-head, a hooked spring-actuated pawl pivoted to the head, a trip-bar connected to the rake-frame in position to trip the pawl, a lifting-ratchet secured to the rakeaxle, and a lock-bar connected to the rakeframe and adapted to lock with the pawl when the teeth fall to theirnsed position, sub stantially as set forth.

2. In a selfiduinping rake, the combination of the ratchet secured to the wheel'axle, a spring-actuated pawl centrally pivoted to the rake'head and having a hook at each end, and a hooked lock-bar secured in position to lock with the lower end of the pawl, substantially as set forth.

3. A rake provided with a hooked pawl connected with the rake-head and a hooked lock-bar adjustably secured to the frame in position to lock with the pawl when the teeth fall to their used position, substantially as set forth.

4. The combination of the spring-actuated lock-pawl connected with the rake-head, the slotted adjustable lock-bar, and the bracecasting adapted to receive and support the lock-bar, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in presence of two witnesses.

JAMES ANDERSON.
